bbbid简介

bbbid是一个高性能的分布式ID生成器，使用微服务框架kratos开发； 实现 美团Leaf segment算法，可分布式部署，保证高可用；

Leaf Server

环境准备

安装Kratos

详情请参考：https://go-kratos.dev/docs/getting-started/start

更新依赖包：

go get -u github.com/google/subcommands
go get -u golang.org/x/tools/go/ast/astutil
go get -u golang.org/x/tools/go/types/typeutil
go get -u golang.org/x/mod/semver
go get -u golang.org/x/tools/go/packages

生成所有proto源码、wire等等

go generate ./...

导入数据库

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for segment
-- ----------------------------
DROP TABLE IF EXISTS `segment`;
CREATE TABLE `segment`  (
  `ckey` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NOT NULL COMMENT '业务key',
  `type` tinyint(0) UNSIGNED NOT NULL DEFAULT 1 COMMENT '类型：1-自增，2-随机',

  PRIMARY KEY (`ckey`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8mb4 COLLATE = utf8mb4_bin ROW_FORMAT = Dynamic;

-- ----------------------------
-- Records of segment
-- ----------------------------
INSERT INTO `segment` VALUES ('rand', 2, 1000, 14000, '随机ID', 1647680509, 1647680509);
INSERT INTO `segment` VALUES ('test', 1, 1000, 29248000, '自增ID', 1591706686, 1620815148);

SET FOREIGN_KEY_CHECKS = 1;

修改配置文件：mysql和redis配置

    timeout: 1s
  grpc:
    addr: 0.0.0.0:8811
